TL;DR: The new, “cloud” era, DC architectures require more optical interconnections, in systems with higher port density, and networks with more flexibility, in order to unlock stranded capacity, and thus lower overall cost.

TL;DR: This Feature Topic focuses on how SDN is being applied to the optical transport layer both within and between data centers, thus extending the work that until now has only been discussed at the upper network layers.
Abstract: Software defined networking (SDN) is a broad term used to describe dynamic control of discrete computing, storage, switching, routing and/or transport devices to create an optimized network configuration for a given application or amount of traffic. SDN allows the network to automatically react to ever changing demands using a shared pool of resources, rather than relying on static designs to improve scalability and resiliency, while reducing cost. This separation of the control plane from the data plane provides the means to orchestrate a wide variety of network resources across multiple layers and multiple domains to achieve optimal utilization. This Feature Topic focuses on how SDN is being applied to the optical transport layer both within and between data centers, thus extending the work that until now has only been discussed at the upper network layers. Some of its enabling key technologies are also discussed.

TL;DR: This paper forces on challenges and potential enabling technologies for user-participated and service-oriented optical networks, which include network virtualization, service model, architecture, and implementation, user- participated network interface.
Abstract: ICT (Information and Communication Technologies) networks are moving to support data, voice, video converged triple play, service-oriented intelligence of resource sharing, reconfiguration, and user-participated DIY (Do It Yourself) on virtual private network control and management. To accommodate these amazing features, future optical network should provide intelligent control and management for reliable transmission, which may employ user-participated and dedicated end-to-end lightpath such as the UCLP of CANARIE CANET4, also highly dynamic operation facilities for distributed multi-domain interconnecting. This paper forces on challenges and potential enabling technologies for user-participated and service-oriented optical networks. The topics involved include network virtualization, service model, architecture, and implementation, user-participated network interface.

TL;DR: In this article, a wayside Ethernet communications system is presented for use with an optical network, which includes a first and second optical network element connected to the optical network and is adapted to map the Ethernet frames into at least one optical network frame.
Abstract: A wayside Ethernet communications system is presented for use with an optical network. The wayside Ethernet communication system includes a first and second optical network element connected to the optical network. The first optical network element having is adapted to map the Ethernet frames into at least one optical network frame and operable to transmit the optical network frames over an optical supervisory channel of the optical network. The second optical network element is adapted to receive the optical network frames over the optical supervisory channel of the optical network and to extract the Ethernet frames from the optical network frames.

TL;DR: A framework for estimating the energy saving potential of cyclic sleep in access, given the constraints from service requirements and traffic conditions is developed and a few critical components are considered and used for showing the potentials.
Abstract: Energy efficiency has become an increasingly important requirement in designing access networks, both due to increased concerns for global warming and due to increased network costs related to energy consumption. In comparison to the metro and core segments, the access constitutes a substantial part of the per subscriber network energy consumption and is regarded as a bottleneck for increased network energy efficiency. One of the main avenues for reducing network energy consumption, and subject to intense research, is the introduction of load adaptive techniques where network elements/subsystems are powered off during periods of reduced network load. Such techniques are particularly interesting for the access segment which is characterized by low utilization. The combination of large contribution to the overall network power consumption and low utilization implies large potential for exploiting such load adaptive techniques. In this article we develop a framework for estimating the energy saving potential of cyclic sleep in access, given the constraints from service requirements and traffic conditions. A few critical components are considered and used for showing the potentials for cyclic sleep in optical access networks
